ASTOR — A 16-year-old boy described to a 911 operator frantically trying to figure out how to help another teen who had fallen out of a boat that capsized last week on Lake Schimmerhorn.

"He was still on the surface, but he was struggling and his older brother was trying to help, but he couldn't help because neither of us can really swim," Jarred Cook, 16 of Altoona, told the operator. "I was looking around for flotation devices and he was already under water when I came back. I didn't see him, so that's where I guess he was."

Nathaniel Ladesic, 14, drowned after the mishap Thursday night. He and his brother, Eli Ladesic, 17, and Jarred had taken the 10-foot jon boat out for the first time when it began to take on water, according to the Florida Fish and Wildlife Conservation Commission. There were no lifejackets or other safety equipment onboard.
